Embodiment Construction

[0031]In the prior art, it is known to fit a sensor on a guide wire and place the sensor through the guide wire in a blood vessel of the human body to detect physical parameters such as blood pressure and temperature. Sensors include elements that are directly or indirectly sensitive to parameters. The applicant of the present patent application is aware that there are many patents describing different types of sensors for measuring physiological parameters. For example, temperature can be measured by observing the resistance of a conductor with a temperature sensitive resistance as described in US-6,615,067. Another exemplary sensor can be found in US-6,167,763, where blood flow applies pressure to the sensor which transmits a signal indicative of the applied pressure. In order to power the sensor and communicate signals representing measured physiological variables to the external physiological monitor, one or more cables or wires for transmitting signals are connected to t...

Abstract

Pressure measurement system comprising a pressure sensor wire with a pressure sensor to measure pressure inside a patient, and to provide measured pressure data to an external device. The pressure sensor wire is adapted to be connected, at its proximal end, to a transceiver unit that is adapted to wirelessly communicate via a communication signal with a communication unit arranged in connection with an external device, in order to transfer measured pressure data to the external device. The pressure data to be transferred is generated by the transceiver unit and transferred as a data stream. Preferably, the communication signal is a radio frequency signal.

Description

technical field [0001] The invention relates to a transceiver unit and a communication unit of a stress measurement system for measuring physiological variables of a human body, according to the preceding independent claims. Background technique [0002] In many medical procedures, medical personnel need to monitor the current physiological parameters in the patient's body cavity. These physiological parameters are typically physical in nature - eg pressure, temperature, flow rate - and provide the physician or medical technician with important information about the patient's condition. Obviously, methods of measuring and monitoring these types of parameters must be safe, accurate and reliable. [0003] One widely used device for monitoring this parameter is a blood pressure sensor. The blood pressure sensor automatically detects the range of the patient's blood pressure and converts it into a typical electrical signal. This electrical signal is then provided to a vital s...
